This definitely wasn't in the Keynote. Jobs simply said that everyone at the conference was going to get a free "Developer Preview". I suspect it's possible that everyone in the Developer Connection channel will have access to a similar deal, perhaps at a fee, but I haven't heard anything about this.

I'm not sure what the legality of "sharing" a copy of the developer's preview is. I strongly suspect that the license prohibits this.
